ALBERT COOK, OF HOLYOKE, MASSACHUSETTS.

Application filed December 10, 1921.

To all 'whomfi' may concern Be it known that l, Ammer Coon, a citi Zen of the United States, and resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Band- Tying Gauges, of which the following isa speciiioation.

This invention relates to improvements in gauges for use in tying driving bands, oi' band-driven machines, with a regulated tension, the improved device being especially adapted for use in tying the spindle driving bands olf spinning or twisting frames.

The invention has tor its object to provide a simple and durable device oit` the character set forth so constructed as tol decrease the labor and time required in tying bands.

In the drawings Fig. 1 is a side elevation of the device attached to a spindle bearing and spindle rail ready for use;

The device comprises an attachment and positioning member 1 which is slotted at its lower end and provided with lugs Q at the opposite vertical sides ot the slot. Between these lugs the lower end of a swinging tension-regulating member 3 is pivotally` held by a suitable pivot pin 4. A. horizontal bracket 5 is carried by the member 1 near its lower end, said bracket being on the op posite side of the member 1 from the tension member and adapted to extend under the spindle rail. l The bracket 5 is formed with two lugs 6 which extend through the slot inv the member 1 and are secured in position by the pivot pin 4l, The lugs 6 snugly lit the slot so that there can be no free up,-

and-down-movement of the bracket 5 indeversely as the diameter of the spindle beary ing, but has considerably greater length to facilitate its engagement with the bearing when the device is in position for use.

The tension member 8 is formed with an extension or abutment 10 at its lower end which is adapted to engage the upper wall of the slot in the member 1 between the lugs 6 and to serve as a stop to limit the outward and downward swinging movement of thev tension member away from the support or positioning member 1. rllhe tensionmember 3 is mounted on the pivot fl between the lugs 6, as clearly shown in Fig. 5. The tension member 3 is normally swung away from the support or positioning kmember 1, to the limit of the movement permitted by the lug 10, by a tension-regulating spring 11. One end of this spring is confined in a 'socket 12 formed in the member 1, and the other end thereof is confined in a socket 18 formed in an externally threaded plug or nut 14 screwed into the outer end or a cylindrical bore or passage 15 extending through extension member 3, said bore or passage being formed in a cylindrical enlargement 16 of said member. The nut 141 is provided with an interior angular', longitudinally-entendA ing projection 17 which is adapted to been-4 gaged by a wrench for adjusting the nut to vary the tension of the spring 11. Said wrench must be inserted through an aperture in the member 1 and longitudinally through the spring and passage 15.

rlhe member 1 is provided intermediate its ends and en its inner face, that is to say, on the face which is placed next to the rail of the spinning frame, with a rotatable adapter 18. This adapter is provided with straight bearing faces 19 and 20, said faces being at right angles to each other and located different distances from the center of the pivot of the adapter. The adapter is formed with two stop shoulders 21 and 22 which are designed to engage a stop in 23 mounted in the member 1. The adapter is also provided with two inwardly extending pins 24, said pins being aligned with they face 19. The

aligning faces of said pin are arranged a suitable distance from the center of the pivot of the adapter7 for a purpose which will hereinafter appear. The band tying device is designed to be placed in position with the outer edge of the rail of the spinning frame against the inner face of the member 1; the under surface of the spinning rail engaging one of the bearing faces of the adapter. The purpose of providing the rotatable and adjustable device 1S is to adapt the device for use with spindle rails of different thick nesses. As shown in Fig. 6, the device is de signed for use with a narrow or thin spindle rail. By rotating the adapter to the position indicated in dotted lines in Fig. 6, it will be adapted for use with a rail of greater thickness. By arranging the device as shown in Fig. 6, pins 24 may be brought into engagement with the bottom of the rail if said rail is too thick to be engaged by the bear* ing surface 19, but is too thin to be engaged by the bearing surface 20. By the use of this simple rotatable device the gauge may be adapted for use on almost any spindle rail now in use. The adapter is pivoted to the member 1 by means of a tubular rivet or pivot bolt 25; and this pivot is made tubular in order that a suitable key may be passed there-through for the purpose of adjusting the nut 14. said pivot being substantially in line with the nut and with the bore 15 when the tension regulating member is in latched position, as will be hereinafter described.

The member 1 is provided at its upper end with an integral bracket 26 which is designed to project rearwardly or inwardly over the spindle rail when the device is in operative position. The bracket 26 is cut away at its free end to form a notch or recess 27 adapted to bearvagainstthe spindle bearing 28 between the rail 9 and thespindle whorl 29 and close to the said whorl. Secured to the upper surface of the bracket 26 is a plate 30. the free end of said plate being cut out or notched as at 31 to fit around and engage the spindle bearing 28, said notch being of such size as to accurately center the bracket 26 on the spindle bearing directly below the spindle whorl, The plate is secured to the upper surface of the bracket 26 by screws 32; and its free end is formed with the upwardly and inwardly eX- tending guard lugs 33 which fit over the lower flange of the whorl at diametrically opposite points. The purpose of these guard lugs is to prevent the band slipping down under the lwhorl during the tying operation and also when the tying band is released from the tying device and connected to the whorl.' These guard fingers quite closely embrace the lower flange of the whorl and'A prevent the spindle being lifted in its bear ing so that the whorl is held in a substantially fixed vertical position with respect to the tying device. The plate 30 is formed with longitudinal side flanges 34 which serve to stiften and straighten said plate.

rlhe upper surface of the bracket 26 is cut away on each side to form the horizontal shoulders 35 directly below the plate 30. Secured to each side of the bracket 26, by means of screws 36 and bearing on the shoulders 35 is a spring side arm 37. The free ends of these side arms are bent inwardly toward each other and then back upon thema selves to form triangular gripping jaws 33. These jaws are adapted to be forced over the spindle bearing and to yieldingly engage it in order to hold the tying device in position.

The member 3 is provided at its upper end with an arm 39 carrying at its inner or free end an upwardly extending tying hook 40 around which the spindle driving band is passed in the operationl of tying the band, as indicated in Figs. 3 and 9. The free end of the arm 39 is beveled outwardly and downwardly to form a cam surface 41 adapted to engage and ride over the upper end of a vertically slidable latch 42 and to depress said latch against the pressure of springs43 when the member 3 is swung toward member 1. The arm 39 is provided with a locking shoulder 44 which is adapted to snap back of the latch bar 42 to lock the tension member 3 against movement after the same is swung a predetermined distance toward the spindle. The latch 42 is confined in a channel formed in the member 1; and the springs 43 are mounted in sockets in said member. as shown in Fig. 7. A pin 45 mounted in member 1 and engaging in a slot 46 in the latch bar 42 serves to limit the movement of said bar. The latch bar 42 at its lupper end is provided with two outwardly extending finger pieces 47, one on each side of the arm 39. and said Enger pieces are adapted to be depressed by the operator when he desires to release the tension member from the latch 42.

A. sheet metal cast-off angle lever, or dofer, 48 is pivoted by a pin 49 to the upper end of the tension member. One arm 48a of said angle lever lies along the upper surface of the tension .member, while the other extends downwardly and outwardly by the side of said lever. The. upper portion of said arm is cut out at its free end to provide Icast-off lugs 50 which lie on either side of the tying bock 40. On the upper member 48"L of the cast-off lever and on each side edge thereof is formed an upwardly extending outwardly projecting guide and retaining hook 51. These hooks are about midway the ends of the upper arm of the cast-off lever and are at each siderof the tying hook. The purpose of these retaining and guiding books is to hold the band on the tying hook during the operation of pulling the ends of the band in `order to place the proper tension on the band. ln Fig. 8 the operation ot these retaining and guidinphoolzs l is illustrated. Spindle driving, bands are usually formed oit two strands twisted together. loop is 'formed at one end and at the other end the two strands are separated. One of 'these separated ends is passed through the said loop in one direction and the other `is passed through the loop in the opposite direction when it is desired to tie the band to the spindle` As shown in Fig. 8, the separated strands, after they have bee-n passed through the loop in the end of the band, are passed outwardly in opposite directions under the ruidi'ng and retainino hooks 51. It is manin b fest thatv these hooksserve to hold the band down on the tyii'ig hook i0 and prevent it sliding` off said hook during the operationv of tying' the band.

The operation of tying the band is as follows:

The lower end of the spindle bearing` 8 is engaged in the aperture '7 ot the bracket 5, and the member l is then swung upwardly to bring' its inner face into engagement with the spindle rail 9 and to cause the spring` jaws 3S to engage `the spindle bearing 28. The recess 27 oi the bracket 26 and the recess 81 of the plate 30 receive the spindle bearing" and all of these parts serve to center 'the member 1 properlyy and to hold it against the spindley rail. The tension member 3 is free of the latch; 42 and the spring 1l vtorces it forwardly, that is to say, toward the operator, and downwardly to the limit of its movement. The lug,- 10 serves as a'limit stop. The spindle driving band is then passed around the drive pulley or cylinder and on opposite sides of the spindle whorl and its ends brought together in 'front ot the tying lug 40. Une strand of the band is passed through the end loop of the band in onev direction and the other strand is passed through said loop in the opposite direction.

These' separated strands are then passed laterally in opposite` directions under the rerlhe operator then pulls outwardly on the said strands. This causes the strands to -bear strongly against the hooks and causes the loop end ot the band to engage the tying hook,A It will be unde-rstood that as strain is put on the separated strands they are pulled out or unravelled from the mainbody of the'band. This shortens the band and puts a strain on the tying lug which throws the tension member upwardly and toward the spindle. It sometimes occurs that the looped end ot the band will remain between the retaining lugs or hooks duringthe tying operation and will not entra-ne the tying; lug'. .ln this event the strain of the strands on the retaining lugs will force the tension member upwardly to its latched position and the looped end of the band will engage the tying lug when the strain on the two strands is relieved. The amtaintl of tension required to throw the tension member to its latched position will depend upon the adjust-ment of the spring il. TWhen theband has been contracted sufficiently to place the desired amount ot tension on the tension member, said member will have been swung,r upwardly to its latched position, as illustrated in Fig. 3. This takes the tension of spring l1 off the band and the knot may then be completed by tying the two strandsI together as indicated in Fig. 9. The tying;a of the band is then completed and by forcing the the member 3,'the'cast-ol lugs 50 will lift i the tied band off the tying lug and allow it to drop between the flanges of the spindle whorl. The gua-rd lugs 38 prevent the band drawingdown under the whorl during the tying operation and also prevent the whorl and spindle being' lifted during the tying operation. Tithout the guards 33 itr was found that sometimes during the tyingr operation the band would slip under the whorl. As ordinarily mounted, the spindle has a slight vertical play and sometimes the whorl and spindle were lifted during the tying operation and this resulted in the band slipping under the whorl. p

When the tying operation is completed and the. band has been released Jfrom the tying lug, the latch plate i2 is depressed and the tension member thereby released. rllhe device may then be quickly removed from the spindle. Of course, the device may be removed from the spindle without?releasing the tension member, but it is thefusual practiceto release the tension member and to allow the liclr, produced by the tension member iiying outwardly` to release the device trom the spindle.`
